Silicon metal is very rich in the earth's crust, rank only second to oxygen. Silicon metal can be divided into many kinds, including ferro silicon etc.Its main element is Si whose content is about 98% and its impurities is Al, Fe, Ca etc. The additional product of silicon metal includes silica fume, edge leather, black silicon etc.Silica fume is widely used in the fireproofing and concrete industry.

production application
(1)Silicon metal can be used to make silicon crystals, silicone rubber , silicone oil etc.
(2)Silicon metal can be used in the aluminum alloy industry.
(3)Silicon metal can also be used as the basic raw material in the chemical industry.
(4)Silicon metal can make high purity semiconductor.
(5)Automobile industries use aluminum that requires a quite large industrial silicon , so the country's auto industry development has a direct effect on industrial silicon market
(6)Silicon metal can replace pure aluminum in steelmaking.
(7)A large proportion of silicon metal will be applied in the chemical industry.
